Review: Perfect size for smaller MC! - I use this on a 2021 Zero FX, essentially a medium sized dirt bike (450, 300, etc..). I was looking for something that didn't look crazy big on the rear fender of the bike but still had useable storage capacity. The soft sides allow it to expand vertically several inches and it will hold a full face helmet without a problem. When its empty or only has small items the soft sides collapse down and give it a much more compact profile. The bag has a bit of a wedge shape which matches the profile of the rear fender much better than a square or rectangular bag, which, combined with the lower collapsed profile looks great and matches the look of the MC. I ordered this bag as well as this Kemimoto 30L Expandable bag (https://www.desertcart.com/dp/B085997KQJ?psc=1&ref=ppx_yo2ov_dt_b_product_details) at the same time to compare. The Kemimoto is a slightly larger capacity bag which would be useful, but the boxy cube look does not compliment the rear fender of my narrower motorcycle. The bungee string on the top of the bag has turned out to be more useful than I thought it would be. There is a velcro panel on the top that opens easily to reveal a great pocket for quickly storing gloves or other small items. I custom mounted this bag to the rear rack already on my MC. I cut some thin aluminum sheet metal to match the rack deck, placed the aluminum piece inside, on the floor of the bag, and bolted through the aluminum, through the bag, and onto the rack so this bag is hard mounted per se. So I don't worry about leaving it in a public parking lot. But I wouldn't leave anything of great value inside as there is no way to really lock the bag. I also don't ever remove the bag so the supplied shoulder straps allowing it to be used as a backpack will never be used, but its an interesting idea. I don't know how this bag would work mounted to the MC with the supplied straps, I don't think I would care for that to much on my particular bike.
Review: It works - Good quality. Appears sturdy and functional. The capacity is capable of holding an extra helmet. I have not used this overtime yet, the jury is out on deliberations on its durability.

## Questions & Answers

**Q: What is the liter capacity?**
A: Not sure of the leaders but I've had a full size full face movable mandible adult helmet and a half helmet in the bag

**Q: What are the 2 bungee cords with clips for?**
A: Nice bag and style look on the bike

**Q: How does it mount to a rear seat on a Honda 750 Aero?**
A: I have mine on a 650 Royal and Royal Enfield 650 Interceptor on the luggage rack and it's just attaches with four straps that you can Quick Clip on or Quick Clip off and then it expands with four additional straps to about 14 inches high so you can put your helmet and other stuff in there at the same time but it's the universal fit

### ⭐⭐⭐⭐⭐ Works for me!
*by R***Y on July 10, 2023*

This bag has been mounted on my Ninja 400 for about a week now and so far it’s doing the job. I got it so I could lose the backpack on my long commute, which I find it much more comfortable to ride without a heavy backpack on! We will see how it holds up over time but I’m happy with it so far. It *does* hold my size XL full face LS2 helmet (2nd) pic although it is a pretty snug fit and takes a little persuasion to get it completely zipped but can be done. For occasional helmet storage it’s probably fine but if you’re wanting to use it for helmet storage daily I’d suggest looking for something bigger. Overall solid product for the money!
